Mobile nodes such as mobile phones, laptops etc are widely used nowadays. Theservices must be always available, reliable and uninterrupted. The communication must besecure. Fault tolerance is the most important feature of these systems. To make a systemfault tolerant at operating system level we apply check pointing. Security threats likeinformation leakage, information theft, information change can be done by a malicious nodeat the time of communication between two legitimate nodes...

[texts]Design and Performance Evaluation of an Efficient Home Agent Reliability Protocol
Mobile IPv6 will be an integral part of the next generation Internet protocol. The importance of mobility in the Internet gets keep on increasing. Current specification of Mobile IPv6 does not provide proper support for reliability in the mobile network and there are other problems associated with it. This paper proposes “Virtual Private Network (VPN) based Home Agent Reliability Protocol (VHAHA)” as a complete system architecture and extension to Mobile IPv6 that supports reliability and of...

[texts]Analysis and Enhancements of Leader Elections algorithms in Mobile Ad Hoc Networks
Mobile Ad Hoc networks (MANET), distinct fromtraditional distributed systems, are dynamic and selforganizingnetworks. MANET requires a leader to coordinateand organize tasks. The challenge is to have the right electionalgorithm that chooses the right leader based on variousfactors in MANET. In this paper, we analyze four leaderelection algorithms used in mobile Ad Hoc Networks. Factorsconsidered in our analysis are time complexity, messagecomplexity, assumptions considered, fault tolerance andti...

[texts]New Fault Tolerance Approach using Antecedence Graphs in Multi Agent Systems
Mobile agents are distributed programs which can move autonomously in a network, to perform tasks on behalf of user. They are susceptible to failures due to faults in communication channels, processors or malicious programs. In order to gain solid foundation at the heart of today’s e- society, the mobile agent technology must address the issue of fault tolerance. Checkpointing has been widely used technique for providing fault tolerance in mobile agent systems...

[texts]A General Mathematical Model for the Simulation of Common Faults in ThreephaseVoltage Source Inverters
In the last years the fault problem in power electronics hasbeen more and more investigated both from theoretical andpractical point of view. This paper analyzes the problem offaults modeling in a three phase voltage source inverter(VSI)and presents a model of a VSI able to simulate both unfaultyand faulty conditions when one or more devices go broken.In the past the fault problem was faced step by stepconsidering the fault on each single device building a modelfor each case...

[texts]Numerical simulations of drainage flows on Mars - Parish, Thomas R.
Data collected by Viking Landers have shown that the meteorology of the near surface Martian environment is analogous to desertlike terrestrial conditions. Geological evidence such as dunes and frost streaks indicate that the surface wind is a potentially important factor in scouring of the martian landscape. In particular, the north polar basin shows erosional features that suggest katabatic wind convergence into broad valleys near the margin of the polar cap...

[texts]Space history, space policy, and executive leadership - Kraemer, Sylvia K
A lecture that attempts to establish the role of space historians in formulating space policy is presented. The discussion focusses on two adages and their relevance to space policy. The adages are as follows: 'write about what you know;' and 'good managers do things right; good executives do the right things.'

[texts]Thermal Emission Variability of Zamama, Culann and Tupan on Io Using Galileo Near-Infrared Mapping Spectrometer (NIMS) Data - Ennis, M. E.
The Jovian satellite Io is the most volcanically active body in the Solar System. Previous analyses [e.g., 1-4] indicate the presence of high-temperature silicate volcanism on Io, similar to silicate volcanism occurring on Earth. Instruments onboard the Galileo spacecraft, especially the Near Infrared Mapping Spectrometer (NIMS) and the Solid State Imager (SSI), provided much data of Io s active volcanoes throughout the duration of the Galileo mission (June 1996-September 2003)...

[texts]Intensity Biased PSP Measurement - Subramanian, Chelakara S.
The current pressure sensitive paint (PSP) technique assumes a linear relationship (Stern-Volmer Equation) between intensity ratio (I(sub 0)/I) and pressure ratio (P/P(sub 0)) over a wide range of pressures (vacuum to ambient or higher). Although this may be valid for some PSPs, in most PSPs the relationship is nonlinear, particularly at low pressures (less than 0.2 psia when the oxygen level is low)...

[texts]Joint for a variable geometry truss and method of constructing same - NON
A joint and a method of constructing a joint for a variable geometry truss having a variable number of planes of variable length battens connected together in a triangular configuration, each plane being connected by six fixed length longerons in a Stewart platform configuration, are presented. The variable length battens allow the orientation of one end plane of the variable geometry truss to be changed to the other end plane in a controlled manner by selectively adjusting the lengths of the va...

[texts]Managing Multiple Tasks in Complex, Dynamic Environments - Freed, Michae
Sketchy planners are designed to achieve goals in realistically complex, time-pressured, and uncertain task environments. However, the ability to manage multiple, potentially interacting tasks in such environments requires extensions to the functionality these systems typically provide. This paper identifies a number of factors affecting how interacting tasks should be prioritized, interrupted, and resumed, and then describes a sketchy planner called APEX that takes account of these factors when...

Test engineering for fault tolerant VLSI systems isencumbered with optimization requisites for hardwareoverhead, test power and test time. The high level quality ofthese complex high-speed VLSI circuits can be assured onlythrough delay testing, which involves checking for accuratetemporal behavior. In the present paper, a data-path basedbuilt-in test pattern generator (TPG) that generates iterativepseudo-exhaustive two-patterns (IPET) for parallel delaytesting of modules with different input con...

[texts]Genetic Evolution of Shape-Altering Programs for Supersonic Aerodynamics - Kennelly, Robert A., Jr
Two constrained shape optimization problems relevant to aerodynamics are solved by genetic programming, in which a population of computer programs evolves automatically under pressure of fitness-driven reproduction and genetic crossover. Known optimal solutions are recovered using a small, naive set of elementary operations. Effectiveness is improved through use of automatically defined functions, especially when one of them is capable of a variable number of iterations, even though the test pro...

[texts]Three-dimensional trajectory analyses of two drop sizing instruments: PMS OAP and PMS FSSP - Norment, Hillyer G
Flow induced distortions of water drop fluxes and speeds seen by the instruments were predicted by use of three dimensional flow and trajectory calculation methods. Sensitivities were determined for the instruments, in isolation and mounted under the wing of an airplane, to: water drop diameter (2 to 1000 microns), angle of attack and free stream air speed. For the optical array probe in isolation and on the airplane at 0 deg angle of attack, flux distortions of practical consequence are not fou...

[texts]Hollow cathode operation at high discharge currents - Friedly, Verlin Jo
It was shown that ion thruster hollow cathode operation at high discharge current levels can induce reduced thruster lifetimes by causing cathode insert overheating and/or erosion of surfaces located downstream of the cathode. The erosion problem has been particularly baffling because the mechanism by which it occurs has not been understood. The experimental investigation described reveals the energies of the ions produced close to the cathode orifice can be several times the anode-to-cathode po...

[texts]Modelling and simulation of Space Station Freedom berthing dynamics and control - Cooper, Paul A.
A large-angle, flexible, multibody, dynamic modeling capability has been developed to help validate numerical simulations of the dynamic motion and control forces which occur during berthing of Space Station Freedom to the Shuttle Orbiter in the early assembly flights. This paper outlines the dynamics and control of the station, the attached Shuttle Remote Manipulator System, and the orbiter. The simulation tool developed for the analysis is described and the results of two simulations are prese...
